Conventional corn production assumes usage of standard inorganic fertilizers which can be added to the soil by different methods. Unlike conventional production, this research was conducted with assumption that by using different application rates of basic and liquid starter fertilizers, as well as, with improved method of their application, higher yield values and lower moisture content of harvested kernels would be realized. This paper explored influence of mechanized application with different rates and ways of broadcasting basic and liquid starter fertilizer to the soil for corn production. Liquid starter fertilizers were applied concurrently with plantation in two ways: in lanes and spots individually for each plant. The results obtained show that kernel yield was higher in areas where starter fertilizer application was performed for 1.79 t·ha-1, while kernel moisture contents was 3.6% lower compared to results obtained over control surfaces.
